The Spectra Precision LL1505C-1 is a contractor-grade rotating laser level package engineered for professionals who demand accuracy and range on large-scale job sites. Delivering a 2,600-foot working diameter and built on a fully rechargeable power platform, this kit covers everything from commercial concrete forming and mass grading to building layout and elevation transfer — right out of the box. The included HL450 digital receiver, Android-compatible smart remote, tenths-graduated grade rod, tripod, and rugged transport case make the LL1505C-1 one of the most complete site laser solutions available at this price point.
Overview & Jobsite Applications
Spectra Precision designed the LL1505C-1 for demanding horizontal leveling applications across open job sites. The instrument self-levels within a wide compensator range and holds elevation with the repeatability contractors require for sub-grade preparation, slab pours, and site utilities. Wireless control via the included Android smart remote allows a single operator to adjust grade, rotation speed, and scan angles from up to 200 feet away — eliminating the rod-and-walk inefficiency of traditional setups. Whether you are coordinating a crew on a large commercial pad or fine-grading a residential development, the LL1505C-1 gives you the range, runtime, and remote capability to work more efficiently.

Frequently Asked Questions
- Does the LL1505C-1 support grade or slope applications?
- No — the LL1505C-1 is a horizontal-only rotating laser. It does not offer manual or automatic grade/slope capability. For grade applications, consider the Spectra LL500 or HV302 series instruments.
- What is the effective range of the included HL450 receiver?
- The HL450 digital receiver can detect the laser beam at distances beyond what the naked eye can see, making it effective up to the instrument's full 2,600-foot working diameter under normal outdoor conditions.
- Can I control the LL1505C-1 from an iPhone or iOS device?
- The included smart remote is designed for Android devices. iOS compatibility depends on the app version available at time of use — check the Spectra Precision app store listing for current iOS support details.
- How long does the rechargeable battery last per charge?
- Spectra Precision rates the LL1505C-1 battery system at up to 100 hours of runtime per charge under normal operating conditions, making it suitable for extended multi-day use between charges.
